In particular, embodiments relate to articles of apparel including encapsulated insulation panels made with an aerogel insulation material and methods of making articles of apparel with the encapsulated insulation panels.

BACKGROUND

Insulation for an article of apparel protects a wearer from the effects of cold weather and keeps a wearer warm. The amount and location of insulation on an article of apparel may provide a desired amount of insulative properties for an article of apparel. But, insulation also adds weight and volume to an article of apparel, which in some cases may be undesirable. Therefore, a continuing need exists for innovations in insulation for apparel and methods of making insulation for apparel.

DETAILED DESCRIPTION OF THE INVENTION

The present invention(s) will now be described in detail with reference to embodiments thereof as illustrated in the accompanying drawings. References to “one embodiment”, “an embodiment”, “an exemplary embodiment”, etc., indicate that the embodiment described may include a particular feature, structure, or characteristic, but every embodiment may not necessarily include the particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to affect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described.

As used herein, “disposed over” means that a second layer/material is deposited, formed, or placed over a first layer/material. The contact between the second layer/material and the first layer/material may be indirect (i.e., there may be other layers between the first and second layers/materials), unless it is specified that the first layer/material is “in contact with,” “deposited on,” or the like with respect to the second layer/material. For example, a second layer/material may be described as “disposed over” a first layer/material, even though there are various layers/materials in between the first layer/material and the second layer/material. Furthermore, if a second layer/material is “disposed over” a first layer/material, the second layer/material is formed, deposited, or placed after the first layer/material (i.e., the first layer/material is present before the second layer/material is disposed over it).

An article of apparel may shield a wearer from various environmental conditions, such as, wind, rain, and cold temperatures. In particular, the insulation of an article of apparel may protect and individual from cold temperatures. However, insulation also adds weight and volume to an article of apparel. Increased weight and/or volume may be undesirable in some instances, for example, for articles of apparel manufactured to be worn during athletic activities. Increased weight may be undesirable because it increases the weight an individual must carry during an athletic activity, which may make the athletic activity more difficult to perform. Increased volume may be undesirable because it may limit movement (e.g., arm or leg movement) and obstruct athletic maneuvers (e.g., dribbling, kicking, shooting, or throwing a ball), thus obstructing optimal athletic performance. Moreover, heavy and/or bulky apparel may be uncomfortable to wear, during athletic activities or leisurely activities.

Additionally, the aesthetic appeal of an article of apparel may be influenced by the apparel's insulation. In some instances, an individual may desire a non-bulky, slim-looking article of apparel. The insulation of an article of apparel may be configured to create a slim-looking article.

However, while lightweight, thinner, and/or slim articles of apparel may be appealing, it may also be desirable that an article of apparel provide the appropriate amount of insulative properties to keep an individual warm. The appropriate type and amount of insulation on article of apparel may provide desired insulative properties for an article of apparel. In some instances, lightweight and thinner insulation material may require superior insulation characteristics (i.e., heat conductivity) compared to its heavier and/or thicker counterparts to provide the same degree of insulative properties for an article of apparel.

In embodiments discussed herein, an article of apparel may include one or more encapsulated insulation panels. The encapsulated insulation panels may be lightweight and thin (e.g., approximately 1.5 mm thick). In some embodiments, insulation in the encapsulated insulation panels may include an aerogel material. The insulation may be divided into individual insulation sections that are coupled together and encapsulated between two thin polymeric films. The polymeric films may serve to separate and encapsulate the individual insulation sections, thereby protecting each of them from damage (e.g., mechanical damage, such as puncturing or tearing and/or water damage). Additionally, separately encapsulating individual insulation sections may isolate one or more insulation sections from damage affecting another insulation section (e.g., water damage to a single insulation section may be prevented from spreading to other insulation sections by separately encapsulating insulation sections).

In some embodiments, insulation sections within an encapsulated insulation panel may be aligned using a template to facilitate proper alignment and encapsulation of the insulation sections. In some embodiments, encapsulated insulation sections may be manufactured with a flat press (e.g., a press that applies only vertical pressures and does not move insulation sections during pressing) to prevent undesired shifting or misalignment of insulation sections. In some embodiments, encapsulated insulation panels may be coupled (e.g., bonded) to an article of apparel to provide desired insulative properties for the article of apparel. In some embodiments, encapsulated insulation panels may be coupled to directly to a fabric of a fully or partially completed article of apparel. In some embodiments, encapsulated insulation panels may be coupled to a fabric that is later used to form all or a portion of an article of apparel. In either case, encapsulated insulation panels may be coupled to the fabric so as to create an embossed fabric.

FIG. 1 shows an encapsulated insulation panel 100 according to an embodiment. Encapsulated insulation panel 100 may include one or more insulation sections 102. Insulation sections 102 may comprise an insulation material, such as but not limited to, an aerogel material. In some embodiments, the aerogel material may include a fibrous sheet of aerogel material (e.g., Areotherm® insulation). In some embodiments, insulation sections 102 may be arranged in a spaced apart relationship with gaps 106 located between perimeter edges 104 of insulation sections 102. Perimeter edges 104 of each insulation section 102 define an outer perimeter 105 of each insulation section 102. In some embodiments, insulation sections 102 may have a thickness of approximately 1.5 mm. In some embodiments, insulation sections 102 may have a uniform thickness.

Insulation sections 102 may be coupled together and enclosed within an encapsulation 110. In some embodiments, encapsulation 110 may comprise one or more polymeric materials or layers (e.g., two polymeric films bonded together as discussed herein). In some embodiments, encapsulation 110 may include a sealed perimeter 112 disposed around a group 103 of insulation sections 102. In some embodiments, encapsulation 110 may include interior seals 114 located at gaps 106 between individual insulation sections 102 in group 103. In other words, sealed perimeter 112 and interior seals 114 may provide a sealed frame 116 that couples insulation sections 102 together, separates individual insulation section 102 from each other, and creates a seal around perimeter edges 104 of insulation sections 102. In some embodiments, encapsulation 110 may be waterproof.

FIG. 2 shows a method 200 of making an encapsulated insulation panel 100 according to an embodiment. Although steps in method 200 may be described as a sequential process, some of the operations may in fact be performed in parallel or concurrently. In addition, in some embodiments, the order of operations may be rearranged without departing from the spirit of the disclosed subject matter. In step 202, a sheet of insulation material (e.g., a fibrous sheet of aerogel material, such as Areotherm® insulation) may be cut into individual insulation sections 102 (see e.g., FIG. 3A). Insulation sections 102 may be cut into any suitable shape, such as but not limited to, polygonal shapes (e.g., triangles, squares, rectangles, or hexagons), circles, and ovals). In step 202, individuals insulation sections 102 may be collected to form a group 103 of insulation sections 102. In some embodiments, one or more insulation sections 102 may have a different shape than other insulation sections 102 in a group 103 of insulation sections 102. In some embodiments, one or more insulation sections 102 in a group 103 may have the same shape, but different sizes (i.e., different sized outer perimeters 105). In some embodiments, each insulation section 102 in a group 103 may have the same shape and size.

In step 204, a group 103 of cut insulation sections 102 may be arranged in a spaced apart configuration between a first polymeric film 120 and a second polymeric film 122 (see e.g., FIG. 3B). Insulation sections 102 may be disposed over first polymeric film 120 in a spaced apart configuration and second polymeric film 122 may be disposed over insulation sections 102 such that insulation sections 102 are positioned between first polymeric film 120 and second polymeric film 122. In some embodiments, insulation sections 102 may be in direct contact with first polymeric film 120 and/or second polymeric film 122.

First polymeric film 120 and second polymeric film 122 may comprise a heat sealable polymeric material, such as but not limited to, polyurethane, low-density polyethylene, polypropylene, thermoplastic polyurethane, and blends or co-polymers thereof. In some embodiments, first polymeric film 120 and/or second polymeric film 122 may a thickness of approximately 75 microns. In some embodiments, first polymeric film 120 and/or second polymeric film 122 may have a melting point of approximately 145 degrees C.

In some embodiments, first polymeric film 120 and/or second polymeric film 122 may comprise an ether based thermoplastic polyurethane with a shore A hardness (measured using ASTMD2240) of greater than or equal to 84+/−2, a tear strength (N/cm, measured using a ISO (International Organization for Standardization) 3001:2001) of greater than or equal to MD (machine direction): 1060, CD (cross direction): 1070, a specific gravity (g/cm3, measured using ASTM D 1525) of greater than or equal to 1.20, a softening point of greater than or equal to 95 degrees C., a melting point of greater than or equal to 145 degrees C., a tensile elongation (%, measured using ISO 527-1:2012) of greater than or equal to MD:430, CD:430, and a tensile strength (N/mm2, measured using ISO 527-1:2013) of greater than or equal to MD:23.9, CD:23.8.

In some embodiments, a template 220 may be employed to arrange and align insulation sections 102 on first polymeric film 120 and second polymeric film 122 (or between first polymeric film 120 and second polymeric film). In some embodiments, template 220 may align insulation sections 102 on first polymeric film 120 and be removed before second polymeric film 122 is disposed over insulation sections 102. Template 220 may include one or more openings 222 corresponding to the shapes of the outer perimeters 105 of insulation sections 102 (i.e., exterior shapes of insulation sections 102). In other words, openings 222 may include inner perimeters 224 that substantially match outer perimeters 105 of insulation sections 102. In some embodiments, openings 222 may include inner perimeters 224 that substantially match outer perimeters 105 of insulation sections 102 in a group 103 of insulation sections 102. In some embodiments, openings 222 may define framework 226 corresponding to the shape of a sealed frame 116 of an encapsulated insulation panel 100.

In some embodiments, template 220 may serve to facilitate the creation of a seal between first polymeric film 120 and second polymeric film 122. In some embodiments, template 220 may be disposed over second polymeric film 122 in a press to facilitate the creation of a seal between first polymeric film 120 and second polymeric film 122. In some embodiments, template 220 may serve to facilitate the creation of a heat seal between first polymeric film 120 and second polymeric film 122, as discussed below in reference to step 206. In some embodiments, template 220 may comprise a metallic material, such as but not limited to, aluminum or steel.

In step 206, first polymeric film 120 may be sealed to second polymeric film 122 in a press 230 (see e.g., FIG. 3C). In some embodiments, press 230 may be a heat press and first polymeric film 120 may be heat sealed to second polymeric film 122 in press 230. In some embodiments, first polymeric film 120 may alternatively or additionally be sealed to second polymeric film 122 with an adhesive. In step 206, first polymeric film 120, second polymeric film 122, and template 220 may be disposed in a press 230 between a first press plate 232 and a second press plate 234.

In embodiments including heat sealing, press 230 may be a heat press and first press plate 232 and/or second press plate 234 may supply heat to seal first polymeric film 120 to second polymeric film 122. In some embodiments, heat may be conducted through template 220 to heat seal first polymeric film 120 to second polymeric film 122. In such embodiments, framework 226 of template 220 may facilitate creation of a heat-sealed border (e.g., sealed frame 116) around and in between insulation sections 102. In this manner, first polymeric film 120 and second polymeric film 122 may be heat sealed together between spaced apart insulation sections 102. In some embodiments, template 220 may be an integral part of press 230. For example, template 220 may be integrally formed on or coupled to first press plate 232 or second press plate 234. In such embodiments, insulation sections 102 may be aligned and arranged on/within press 230.

In some embodiments, first polymeric film 120 may be heat sealed to second polymeric film 122 at a temperature in the range of 125 degrees C. to 140 degrees C. In some embodiments, first polymeric film 120 may be heat sealed to second polymeric film 122 at a temperature in the range of 130 degrees C. to 135 degrees C. In some embodiments, press 230 may supply approximately 4.5 kgf/cm² (kilogram-force per square centimeter) of pressure when heat sealing first polymeric film 120 to second polymeric film 122. In some embodiments, heat sealing of first polymeric film 120 to second polymeric film 122 may be performed in approximately 45 seconds. These process parameters may vary depending on the material(s) comprising first polymeric film 120 and second polymeric film 122 and/or the thicknesses of the first polymeric film 120 and second polymeric film 122. In some embodiments, press 230 may be a flat press (i.e., a press that does not move insulation sections 102 during pressing and applies only vertical pressure with press plates 232/234 in a direction perpendicular to the thickness of insulation sections 102).

After first polymeric film 120 is sealed to second polymeric film 122 in step 206, insulation sections 102, first polymeric film 120, and second polymeric film 122 may be removed from press 230 in step 208 (see e.g., FIG. 3D). In some embodiments, insulation sections 102, first polymeric film 120, and second polymeric film 122 may be cooled on a cooling table for approximately 10 seconds before step 210.

In some embodiments, as shown for example in FIG. 2, steps 202-208 may produce a semi-finished encapsulated insulation panel 240. In such embodiments, semi-finished encapsulated insulation panel 240 may be cut to remove excess material (e.g., excess portions of first polymeric film 120 and/or second polymeric film 122 around the perimeter of encapsulated insulation panel 100) in step 210 (see e.g., FIG. 3E). Is some embodiments, semi-finished encapsulated insulation panel 240 may be cut using a cutting tool 250 (e.g., a die cutting tool). Is some embodiments, semi-finished encapsulated insulation panel 240 may be laser cut. After semi-finished encapsulation insulation panel 240 is cut to remove excess material in step 210, a finished encapsulated insulation panel 100 is produced (see e.g., FIG. 3F). In some embodiments, step 210 may be eliminated by precisely measuring and positioning insulation sections 102, first polymeric film 120, and second polymeric film 122 in press 230. In some embodiments, press 230 may be configured to cut excess material from first polymeric film 120 and/or second polymeric film 122 before or after sealing first polymeric film 120 to second polymeric film 122.

While FIG. 2 shows the production of a single encapsulated insulation panel 100, method 200 may produce a plurality of encapsulated insulation panels 100. For example, two or more groups 103 of insulation sections 102 may be arranged in spaced apart configurations between first polymeric film 120 and second polymeric film 122 in step 204. In such embodiments, a plurality of templates 220 may be employed to arrange and align groups 103 of insulation sections 102. Subsequently, first polymeric film 120 and second polymeric film 122 may be sealed around and in between insulation sections 102 and groups 103 of insulation sections 102, thereby creating a semi-finished encapsulated insulation panel including a plurality of encapsulated insulation panels 100 coupled together. Then, in step 210, individual encapsulated insulation panels 100 may be cut from the semi-finished encapsulated insulation panel.

FIG. 4 shows a method 400 of making an article of apparel including one or more encapsulated insulation panels 100 according to an embodiment. Although steps in method 400 may be described as a sequential process, some of the operations may in fact be performed in parallel or concurrently. In addition, in some embodiments, the order of operations may be rearranged without departing from the spirit of the disclosed subject matter. In step 402, an adhesive film 450 may be arranged between an encapsulated insulation panel 100 and a first fabric layer 460 (see e.g., FIG. 5A). First fabric layer 460 may be woven, nonwoven, or knitted and may be made of one or more suitable textile materials (i.e., fabric material) including, but not limited to, nylon, polyester, polyamide, polyolefin, acrylic, expanded polytetrafluorethylene (ePTFE), cotton, silk, elastane, wool, any combination, blend, or recycled version of the same.

In some embodiments, adhesive film 450 may include a plurality of openings 452. Openings 452 may have shapes corresponding to the shapes of the outer perimeters 105 of insulation sections 102 in a group 103 of insulation sections 102 (i.e., exterior shapes of insulation sections 102). In other words, openings 452 may include inner perimeters 454 that substantially match outer perimeters 105 of insulation sections 102. Openings 452 in adhesive film 450 may define a framework 456 having a shape corresponding to the shape of a sealed border (e.g., sealed frame 116) around and in between insulation sections 102 of an encapsulated insulation panel 100. In some embodiments, adhesive film 450 with openings 452 may be cut (e.g., laser cut) from a stock sheet of adhesive film. In some embodiments, openings 452 may be formed by arranging strips of adhesive film to form framework 456 having openings 452.

In some embodiments, adhesive film 450 may be a double-sided adhesive film. In some embodiments, adhesive film 450 may be a heat seal film. In some embodiments, adhesive film 450 may be an adhesive film manufactured by Bemis Company, Inc.

After arranging adhesive film 450 between encapsulated insulation panel 100 and first fabric layer 460, encapsulated insulation panel 100 and first fabric layer 460 may be bonded together in step 404 (see e.g., FIG. 5B). In some embodiments, encapsulated insulation panel 100 and first fabric layer 460 may be bonded together using a press 470 (e.g., pressed together to bond encapsulated insulation panel 100 and first fabric layer 460). Press 470 may apply one or more types of pressure to bond encapsulated insulation panel 100 and first fabric layer 460. Types of pressure press 470 may apply include, but are not limited to, mechanical pressure (e.g., pressing encapsulated insulation panel 100 and first fabric layer 460 between two press plates) and vacuum pressure (e.g., pulling a vacuum between two non-air-permeable layers positioned on opposite sides of an assembled encapsulated insulation panel 100 and first fabric layer 460 (see e.g., polymeric pad 602 and polymeric sheet 610 in FIG. 6)). Press 470 may be the same as or similar to press 230. In some embodiments, press 470 may be a heat press. In some embodiments a template the same as or similar to template 220 may be used in conjunction with press 470 to bond encapsulated insulation panel 100 to first fabric layer 460. After bonding, encapsulated insulation panel 100 and first fabric layer 460 may be removed from press 470 in step 406 (see e.g., FIG. 5C).

In some embodiments, the bonding of encapsulated insulation panel 100 to first fabric layer 460 may create an embossed fabric 480 (e.g., a fabric having an outer surface conforming to the shape of insulation sections 102). In some embodiments, the creation of embossed fabric 480 may be facilitated by adhesive film 450 having openings 452 defining framework 456. Framework 456 may result in encapsulated insulation panel 100 being bonded to first fabric layer 460 only at locations corresponding to sealed frame 116 in order to create embossed fabric 480. In some embodiments, the creation of embossed fabric may be facilitated by the application of pressure in press 470 (e.g., by pulling a vacuum and/or by applying mechanical pressure on a template within press 470).

Once encapsulated insulation panel 100 is bonded to first fabric layer 460, the side of encapsulated insulation panel 100 opposite the side bonded to first fabric layer 460 may be coupled to a second fabric layer in step 408 (see e.g., FIG. 5D). In some embodiments, this may be accomplished by coupling a second fabric layer to first fabric layer 460. In some embodiments, the second fabric layer may be bonded to first fabric layer 460. In some embodiments, encapsulated insulation panel 100 may be alternatively or additionally coupled (e.g., bonded) to the second fabric layer.

In step 408, encapsulated insulation panel 100 and the second fabric may be disposed in a press (e.g., press 470) where pressure and/or heat is applied to couple encapsulated insulation panel 100 and the second fabric together (e.g., by bonding first fabric layer 460 to the second fabric layer). In some embodiments, first fabric layer 460 may be bonded to the second fabric layer with an adhesive tape 492 disposed over a perimeter of the second fabric layer such that it overlaps first fabric layer 460 and the second fabric layer. In some embodiments, adhesive tape 492 may be disposed over an outer perimeter (e.g., sealed perimeter 112) of encapsulated insulation panel 100. In some embodiments, adhesive tape 492 may be silicone rubber tape. In some embodiments, adhesive tape 492 may be heat sealing tape. Similar to first fabric layer 460, the second fabric layer may be woven, nonwoven or knitted and may be made of one or more suitable textile materials (i.e., fabric material) including, but not limited to, nylon, polyester, polyamide, polyolefin, acrylic, expanded polytetrafluorethylene (ePTFE), cotton, silk, elastane, wool, any combination, blend, or recycled version of the same.

The coupling of encapsulated insulation panel 100 and the second fabric layer in step 408 may create a multilayer fabric 490. Once bonded, multilayer fabric 490 may be removed from press 470 in step 410 (see e.g., FIG. 5E). In some embodiments, multilayer fabric 490 may be formed on a fully or partially completed article of apparel (e.g., first fabric layer 460 or the second fabric layer may be part of a fully or partially completed article of apparel). In some embodiments, multilayer fabric 490 may be a fabric sheet used to form all or a portion of an article of apparel. For example, fabric sheet(s) 806 appropriately dimensioned for portions (e.g., sleeves, body, or collar) of jacket 800 shown in FIGS. 8 and 9 may be cut from multilayer fabric 490. In such embodiments, appropriate cutting and coupling of fabric sheet(s) 806 along seams 808 may serve to properly position encapsulated insulation panels 100 on jacket 800 (or other types of apparel).

FIG. 6 shows an exploded view of various layers that may be disposed in a press (e.g., press 470) when bonding encapsulated insulation panel 100 to first fabric layer 460 in step 404 according to an embodiment. As shown in FIG. 6, a polymeric pad 602 may be disposed over a first press plate 600 of a press. In some embodiments, polymeric pad 602 may be in direct contact with first press plate 600. In some embodiments, polymeric pad 602 may be a silicone pad. A first fabric layer 604 may be disposed over polymeric pad 602. In some embodiments, first fabric layer 604 may be in direct contact with polymeric pad 602. First fabric layer 604 may be the same as or similar to first fabric layer 460.

An adhesive film 606, which may be the same as or similar to adhesive film 450 may be disposed over first fabric layer 604. In some embodiments, adhesive film 606 may be in direct contact with first fabric layer 604. An encapsulated insulation panel 608 including one or more insulation sections (e.g., insulation panel 100) may be disposed over adhesive film 606. In some embodiments, encapsulated insulation panel 608 may be in direct contact with adhesive film 606. A polymeric sheet 610 may be disposed over encapsulated insulation panel 608. In some embodiments, polymeric sheet 610 may be in direct contact with encapsulated insulation panel 608 and/or a second press plate 612 of a press. In some embodiments, polymeric sheet 610 may be a Teflon sheet.
